Wt

I use an WStandardItemModel for the data i received from an .csv file.

Then, i create an WSortFilterProxyModel to set as Model for a tree,

an get the data in it (with setSourceModel())

following my sample pseudo code:

WStandardItemModel *fileModel = new WStandardItemModel();
readFromCsv(f, fileModel); // fills the ItemModel
m_fileProxyModel = new Wt::WSortFilterProxyModel(this);
m_fileProxyModel->setSourceModel(fileModel);
m_tree->setModel(m_fileProxyModel);

Dynamically i read the .csv file to check if there are any changes,

if an item is added, i just set it in my ItemModel:

m_fileModel->setItem(idx_row, idx_col, item);

and the tree is updated with the new information, without refreshing or something

If an .cvs entry is removed, i try to delete if from my model using "takeItem()"

WStandardItem *toRemove = m_fileModel->takeItem(idx_row, idx_col);
delete toRemove;

But this doesn't effect the tree (if it is the second col)?

If needed, i can provide my full example code and the .csv file
